Now Penrose's twist is that you solve the equations for the very same <br>
experiment in a rocket ship accelerating at 1 g, then you get the same <br>
wavefunction but with a different complex phase coefficient in front of <br>
it. This requires the two situations occur in different vacuums with <br>
different ground state energies. This puts the equivalence principle of <br>
GR and the superposition principle of QM into direct opposition, since <br>
you can't have a superposition of vacuum energies in QM. (Except maybe <br>
in a multiverse? Does an ontological universal wavefunction rescue one <br>
or both principles?)<br>
